i'm glad that you like our articles. they offer room for comparisons.

i believe that the 200 fps' gain in velocity imparts enough momentum to a bullet that it makes a difference. the difference may be in hitting the vitals, or it may be in producing an exit wound. either way i see it as a distinct advantage, particularly if a shot must be made at a bad angle. because additional barrel length is one way of picking up velocity (as is a tight barrel to cylinder gap) without unduly raising pressure, i'll consider it a cheap way to get velocity without putting further strain on the forcing cone, etc.
your short-barrel'd firearms may have tighter barrel/cylinder gaps than the longer barrel'd items that Don't produce the greater velocities. that's no secret to an experienced revolver shooter like yourself, i don't think.
no surprise with the idea that 'shock' is not generated by a handgun. i have never said, i don't think, that it is. but i don't believe for one minute that bullet weight and caliber are the only ways to pick up power. i believe all three of those factors play an important part in terminal ballistics. elmer keith's hot-rodded .44 specials did approx' 1,200 fps'with his 250 gr' bullet, and the .44 mag's started out much higher than that (at approx' 1,600 with a 240 gr' bullet, i believe). and, if you remember, keith went down in caliber from .45 colt to pick up the additional velocity from the stronger .44 special revolvers of his day. that in itself is noteworthy.
j.d. jones has written that his 320 gr' bullet for the .44 mag' can be driven to almost 1,400 fps' in a 7 1/2" barrel'd revolver with safe pressures. he said that it has been demonstrated to kill an elephant. i'm not sure it would work at 1,000 fps' out of a 3" barrel (or whatever...)
iyour 'link' looks like something from john linebaugh's site. i've read his articles. he's a tremendous gunsmith, reputedly a good Christian, and a somewhat accomplished hunter. but he is neither a physics nor a math teacher. and he doesn't always compare apples to apples in his writing. at least in my opinion. and i've read his stuff through more than once. there's more to the .44 mag' vs' .45 colt comparisons than what he seems to understand.
good shooting to you all,
